where the minimization involves all the local observables that act on the subsystem \(A\) . Indeed, \(\Lambda \)  here is non-degenerate because it corresponds to the maximal informational observables of subsystem \(A\) . This quantifier has strong reasons to be considered as a faithful measure of the quantum correlations of bipartite quantum states. Indeed, the local quantum uncertainty is invariant under local unitary transformations, is not increasing under local operations on the subsystem \(B\) , vanish if and only if the quantum state is classically correlated [1]}. For pure states, the local quantum uncertainty is a monotonic entanglement. As a result, the local quantum uncertainty satisfies all the physical requirements for a quantum correlation measure.
